BCM part number lookup?

[timmerk]

Hi all, I just bought a used BCM on eBay and the part that arrived is 20939138, which wasn't advertised on the listing. It's not coming up on any GM part website. Does anyone have access to look it up, and see what part number superseded it? Also, will it work for an 08 GMC Sierra 1500, once programmed? I'm trying to see if it will have full functionality, or if I should go through the hassle of returning it. Thanks!

Any BCM will have to be programmed to your vehicle.

 

Plug your VIN in here: https://parts-catalog.acdelco.com/acesCat.php?#

Yes, I didn't want to program it yet before verifying because the ebay seller won't accept returns of BCMs once programmed.

[swathdiver]

Using the ACDelco link and your provided information, they listed 2 or 3 part numbers and neither were that one.  If you are still interested in seeing what that number goes to, plug in the number at GMPartsDirect.

Thanks, but that's what I'm trying to say - the part doesn't exist on any GM part website, including GM Parts Direct. It has been superseded, so if I look up BCM part numbers today, it will show me the new ones, not all the old part numbers that once worked. I'm basically asking if a GM parts guy that has more access can look up the part number.

I did a google search and found lots of stuff on that part number. Sure the older part number can't be found on the GM site but that BCM is on my other sites as it was used in a ton of trucks.

 

Maybe a guy on here can give you the more or just call the dealerships part department in the morning.

Thanks, I'll try calling, as all the stuff I found on Google are on salvage reseller websites, and they contradict each other (some say it works on 08 GMC Sierra's; others say the part doesn't.)

[dna9656]

Chevy customer service: 1 800 222 1020 I think.

Anyway, these folks will do all they can to help you.

When I can find that elusive number, it is only associated with the wagons, not the pickups.

Ahh, that makes sense! This is supposed to be from a Yukon SUV. I wonder why GM does that?

[richard wysong]

probably has something to do with the rear air or the tailgate
